From dd3daca162f7411448dd80a8872a002c43cfd8e5 Mon Sep 17 00:00:00 2001 From: Jingoo Han Date: Fri, 24 May 2013 10:10:13 +0900 Subject: dma: use platform_{get,set}_drvdata() Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev, so we can directly pass a struct platform_device. Also, unnecessary dev_set_drvdata() is removed, because the driver core clears the driver data to NULL after device_release or on probe failure.
